COLD-STORAGE HOUSE.

SPECIFICATION forming part of Letters Patent No. 433,316, dated July 29, 1890.

Application filed March 6, 1890. Serial No. 342,829. (No model.)

To all whom, it may concern:

le it known that I, ALBERT W. BLACK, ot'

' the city of St. Louis, in the State of Missouri,

have invented a certain new and useful Improvement in Cold-Storage Houses, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specilication.

My invention relates to certain improvements in the arrangement and construction of cold-storage houses or permanent refrigerators; and my invention .consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a vertical section illustrative of my invention. Fig. II is a horizontal section taken on line II II, Fig. I.

In making my present invention I have had in mind or view the idea of making such a structure in which the foul odors and dampncss from the cellar and sides of the box, as well as the heated air in the walls, which may be due to outside influences, are removed or carried oit and not permitted to enter the storage-chamber; also, the the idea of making such a structure in which the supportingbeams to the ice-iioor may bc put in position after all the other work on the walls, tbc., has been finished; also, the idea of producing an iron floor in the ice-chamber, which is constructed to drain the melted ice to a deliverytrough, and by means of Which theice-box is made water-tight at bottom at a Very small cost; also, the idea of producing a ceiling or roof to the ice-box so inclined as to produce a circulation of air around and from the icebox to, through, and from the storage-room, and, also, the idea of producing circularformed corners to the upper portion of the ceiling, which facilitates the circulation, without the condensation of dainpness at such points; and with these objects in view I have produced the construction which I will now describe, having reference to the drawings.

l represents the outer walls of the structure, having a roof or canopy 2. These walls and thiscanopy are constructed with passages or fines 3, through which the damp and foul air from the cellar of the struc-ture pass and escape through openings 4f. at the upper portion of the structure, as shown in Fig. I. These tlues and passages also carry off the heated air of the walls which may be formed, or due to outside influence or temperature of the atmosphere, and thus afford a protection 1n the Way of excluding warmth from the icebox and storage-room. After the Walls and canopy of the structure are formed I place within the lower portion of the walls a fraining 5, consisting of suitable vertical and horizontal strips or beams, and upon this framing the Supporting-beams G of the ice-chamber are placed after the work on the outer walls and canopy has been completed. By thus constructing the support for the ice-box it 1s not in the way and does not interfere with the work on the walls and the canopy, as the beams are not put in place until after such work has been completed.

7 represents the ice-box, which rests on the beanis. The floor of this box is lined with galvanized iron strips S, placed diagonally across the floor of the box, with the lower edge of each strip lapped over the adjacent edge of the strip beneath, as shown in Fig. I, and also by dotted lines in Fig. II. At the lower side of the inclined ioor of the ice-box is locatedV a trough 9, which carries the melted ice to .a suitable delivery-spout, and through which it is transferred away from the box, the lower side of one wall of the ice-box being provided with a suitable number of leak ports or ducts 9a, leading from the lower end of the ice-box into the trough. By thus constructing a door it. will be seen that the water will pass from one strip onto another and there will be no tendency for it to leak through between the overlapping edges of the strips, as there is a downward incline from each of the joints. lining thus formed is exceedingly cheap 1n structure and can be quickly applied.

The roof or top 10 of the ice-box is made inclined, as shown in Fig. I, and at the top of the lower side of the ice-box there is an opening l1, through which the cold air may pass from the ice-box to the storage-room 12. 13 represents a ilue or chamber at the back, top, and front of the ieechamber. The air circulates from the storage-room up behind the ice-box, thence over the ice-box, and thence down in front of the ice-box into the storage- IOO room again. The beams 6, of course, are placed a short distance apart and the air circulates between them. As the air circulates around the ice-b0X,itis chilled or cooled, and owing to the inclination of the top of the box a natural draft is created to produce the circulation, as shown by the arrows. :While this air, which is necessarily Warmer than the air Within the ice-box, Will not enter the icebox, yetthe 'surplus of air in the ice-box Will escape through the opening Il and pass into the storage-room. The ceiling of the housing is provided With rounded corners I4, which assist in the perfect circulation ot' air from the storage-room around the ice-box and prevents the collection of dalnpness and condensation of moisture at these points.

With a structure of this kind I produce a cold-Storage house wherein there is a perfect circulation Without ventilation and Without the introduction of outsidey air, .the result being a very great lsaving of ice and a more perfect refrigeration of the contents ofthe storage-room, and sweat in the ice. box or chamber isalso avoided, because no warm air comes in contact with the ceiling of the icechamber. It will be seen that all the roofs or tops are substantially parallel and inclined in I but one direction, so that there Will. be no counter-currents around the ice-box.

I lclaim as my inventionl. In acold-storage house, the combination ofJthe outer Walls-and canopy provided with air-passages and an inner ice-box and storage-room closed from communication with the outside atmosphere, said ice-box and storage-chamber having parallel inclined ltops with a space between them, substantially as set forth.

2. In a cold-storage house, an ice-box having an inclined floor provided with a lining composed of overlapping diagonally-arranged strips and a trough at the lower side of said iioor, substantially as and for the purpose set forth.

3. In a cold-storage house, the combination of the outer Walls and canopy, an ice-box and storage-room located within the outer Walls and canopy, said.icebox having an imperforate roof or top inclined in but one direction and forming an inclined air-passage between the top of the ice-box and the canopy of the housing, and the latter canopy being also inclined in but one direction, substantially as and for the purpose set forth.

et. In a cold-storage house, the combination of the outer Walls and canopy forming a housing and an ice-box and storage-roomlocated t within the housing, the ceiling of said housing having rounded corners I4, and both the ceiling of the housing and the top of the iceboX being imperforate and inclined in but one and the same direction, substantially as and for the purpose set forth.

5. In a cold-storage house, the combination of the outer Walls having air-inletsat bottom and top, respectively, an inclined canopy or roof arranged on said Walls, the inner walls arranged at a distance `from the outer Walls and provided with a closed bottom or i'loor and a closed top or roof inclined in but one direction, forming an inner room or chamber having no communication Whatever with Athe space between the inner and outer Walls or with the external atmosphere, the independent framing 5, arranged Wholly Within the against communication with the said inner chamber save through the said side opening Il, substantially as and for the purposes set forth.
